HAMAS and Hisbollah have been building rockets in Gaza for some time now. They have been using them against Israeli settlements and farms. Eventually, they will perfect one capable of bringing down an airliner.
If some terrorist tries to bring down an airliner we will NEVER hear about it.
Or it will be the typical deal where a news item leaks like this one and then everyone starts screaming at us to don our tin foil hats.
